WPF：打开文件App.xaml，添加MappApps.Metro相关的资源字典时，后三行添加报错

 

 报错如上。

 

错误原因：使用了旧版资源字典地址

解决办法：使用和新版框架配套的资源字典地址

 

效果如下：

 

 代码如下：

<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<!-- MahApps.Metro resource dictionaries. Make sure that all file names are Case Sensitive! -->
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml" />
<!-- Accent and AppTheme setting -->
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Themes/Light.Blue.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
